\VILLIAM ALLEN PENDRY, OF DETROIT, MICHIGAN.

BUTTON-MAKING MACHINE.

SPEQIFIEATIQN forming part of Letters Patent No. 693,565, dated. February 18, 1902.

Application filed March 2, 1901. 8erial No. 491606. (No model.)

To (wt ur/wnt 1 25 may concern Be it known that I, VVILLIAM ALLEN PEN- DRY, a citizen of the United States, residing at Detroit, county of VJayne, State of Michigan, have invented a certain new and useful Improvement in Button-Making Machines; and I declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Myinvention relates to an improved button-making machine, having for its object a machine for this purpose whereby the entire operation of making completed buttons from suitable blanks may be carried out by a single machine rapidly and economically, various operations necessary for the construction of the completed buttons being carried out by the machine in a succession of steps or stages from the feeding of the button-blanks thereto until the finished result is obtained.

My invention has more special reference to a machine for making pearl buttons; but I would have it understood that I'do not confine its scope or application thereto alone, as it may be used for the construction of buttons from other materials.

My invention consists of the constructions, combinations, and arrangements of devices and appliances hereinafter specified and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a plan view showing my invention with the cover removed. Fig. 2 is a vertical section on the line 2 2, Fig. 1, showing parts in elevation. Fig. 3 is ahorizontal section on the line 3 3, Fig. 2.

I carry out my invention as follows:

A supporting-frame may be employed of any suitable construction. As shown in the drawings, it consists of a base a, a spider b, a support 0, a stationary table 01, and a stationary race or track 6, having a connecting spider f, provided with a hub 267. A suitable inclosing case is shown at q, and a top or covering at h. A main driving-shaft is indicated at 2', provided with a driving-pulleyj. A shaft k is provided with a bevelgear Z, meshing with a gearm 'upOn the shaft 1. The shaft 7c is also provided with a non-rotatable bearing-plate n, in which the drivingshaft '11 is journaled at one end, as shown at p. The opposite end of the driving-shaft is journaled in its bearingswithin the case q, as shown. The shaft is journaled at its lower end in the plate 91. and at its upper end in the above the spider with a gear r.

Upon the stationary table d, as shown in the accompanying drawings, are supported a blank-feeding device s, a grinding or backing mechanism I a blank-reversing device to, grinding or facing wheels '0 '0, steel facingtool mechanism to, a series of drilling devices w, a buffer 3 and, if desired, a counter z. I would have it understood that I do not, however, limit myself to any definite number of grinding or facing wheels or to any definite number of cutting and buffing devices or to any specific number of drilling devices, as my invention contemplates any desired number as coming within its scope. The particular construction and operation of the feeding, reversing, facing, cutting, drilling, and buffing devices will be hereinafter described.

The numeral 2 denotes a rotatable turret or table carrying aseries of mandrels 3. In Fig.

Fig. 42 is a view in vertical section on,

1 twelfth of a complete revolution. operating a locking-bolt 16, (both shown in dotted lines in Fig. 2,) engageable with the turret 2, serves to hold the disk 8 and turret from rotation during the intervals of the stop movement of said disk.

spider b and is provided at its upper end '1 1 I have shown a series of twelve mandrels; but I would have it understood that I do not limit myself to any particular number thereof, as my invention contemplates the employment of any desired number of mandrels to be carried by the revolving turret or table. The construction and operation of the mandrels will be subsequently explained. The turret is preferably constructed with an outer rim 55 and with an inner rim 5, the outer rim being preferably of cylindrical form and the inner rim of angular form, as shown. In these rims the mandrels are supported, the

rims being connected by a suitable number of arms 6. The rim 55 travels in its rotation upon the race or track e.

The numeral 7 denotes a rotatable sleeve or hollow axle provided with a toothed disk 8 at its lower end, the upper extremity of the sleeve being rigidly engaged with the turret in any suitable manner. In the drawings the sleeve 7 is shown constructed with a flange 9 at its upper end, which may be secured in any suitable manner to a corresponding flange 10 upon the inner rim 5 of the turret. The sleeve or axle 7 is actuated by means of a ro tatable disk 11 upon a hollow trunnion 12, driven from the shaft 76, as hereinafter explained. The diskS is arranged to be rotated one step at each complete revolution of the disk 11 in any suitable manner. The disk 8 is arranged to be rotated one-twelfth of a complete revolution upon each complete revolution of the disk 11. If twelve mandrels are used, as shown in the drawings, the disk 8 is accordingly provided uponits periphery with twelve recesses or notches 13, as shown in Fig.

21, while a roller pin or tooth 14 upon the disk .11 engages in one of said recesses or notches and carries the disk 8 forward one- Alever 15,

It will be understood that the mandrels 3 are spaced one from another upon the turret a distance apart corresponding to the stop movement of the turret, the various feeding,

grinding, reversing, buffing, and drilling devices located upon the stationary table d being spaced one from another in a similar man- I ner, so that as the turret revolves the mandrels will be moved by successive steps from one to another of said devices upon said table to present the button-blanks carried by the mandrels to said devices in successive order until the button is completed.

The shaft 2' is provided with a sprocket-gear 17 for driving the feeding mechanism. Meshing with the beveled gear Z is a series of gears for driving the grinding, buffing, and drilling mechanisms. Thus to drive one of the grinding devices If I provide a gear 18 upon a shaft 19, meshing with the gear Z. The shaft 19 drives a pair of beveled gears 20, driving a ICC
